SPECIFICATION forming part `ofLetter-s Patent No. 289,657, dated December 4, 1883.

Application nieanugust is, i883. (No model.) v

To all whom it may concern,.-

Be it known that I, GHEIsT HITTINGEP., a

citizen ofthe United States, residing at Day-V to which it appertains to make and use thek same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improved device for extinguishing the fire in a car-stove when l by accident the car is'overturned; and it consists, in its essential feature, ina pivotal reservoir which is discharged by its own gravity when the car to which the same is attached is overturned.

I attain the object by the mechanism illustratedy in the accompanying drawings, in which- Figure l is a side view of the extinguisher as attached to the floor of a passenger-coach. Fig. 2 is a top view of the segmental cog as attached to the stem of the stop-cock.

A represents the floor of a'passenger-coach to which the hangers B B are bolted.

M represents a stove, which may be of avariety of forms, the only essential feature being that a hole in the side, near the top, must be provided for a pipe.

On both ends of the reservoir O are hollow bearings, which are pivoted in the hangers. These bearings are attached to the cylindrical reservoir, near the top of the same. W'ater is poured into the reservoir through a hole in the top (not illustrated) until it reaches the height of the dotted line, and when closed the vessel is air-tight. The ordinary check-valve, D, prevents any escape in that direction, and the ordinary stop-cock, E, likewise closes the discharging-orifice. i

The iiexible pipe I'is attached to the pipe outside of the check-valve, and is connected With a pipe leading from a vIestinghouse airpump. .By this means air is forced into the space above the water, giving a pressure the equivalent of that used to operate the carbrakes. Into the right bearing is screwed the curved pipe F, which terminates near the prevented from escaping from the reservoir .until the wateris exhausted. To the bearing ytothe rightisattached the ordinary stop-cock,

E, and to the stem of which is loosely attached the segmental beveled cog H,' I(top view at Fig.

2,) which is supported on the nut z' on the end 6o ofthe stem. Aportion of the hubis cut away, and within 1 which space alug of the stem of the stopcock plays, andtherefore slight oscillation of the reservoir does not move the plug of the stop-cock.

'lo the hanger B is bolted the segmental beveled cog G, which engages cog H, previously described, and by which gear the valve is opened by the partial rotation of the reservoir in its bearings. rlhe flexible tube J is connected to the iron pipe K, and to this the rose L is connectedwithin the stove, immediately above the nre-box. The check-valve and stop-coclr are rigidly attached to the bearings of the reservoir, and the flexible tubes I and J admit of a comparatively free movement of the reservoir. If metallic connections alone are made, stuffing-boxes must be provided for the connections at both ends.

The operation is thus: Fill the reservoir with water to the dotted line; then turn in the air from the air-pump, which connection may be permanent. The contained water is subjecte'd to great pressure, and when the vcar overturns the gravity of the reservoir causes it to swing in its bearings, thereby opening the stop-cock, which admits of the jetting of the water from the rose onto the fuel contained in the fire-box of the stove, and thus v .my own I affix my signature in presenceof two witnesses.
